基于结构不确定性的非线性鲁棒制导律设计

Design for nonlinear robust guidance law with structured uncertainties

根据多普勒雷达导引头和红外成像导引头多模制导导弹弹道中段制导信息精度的特点,以非线性鲁棒控制理论为依据,设计了一种制导律。仿真结果表明,该制导律对弹目相对距离测量干扰有较好的鲁棒性,对目标大机动也有鲁棒性。因此,这种制导律可以作为多普勒雷达导引头和红外成像导引头多模制导导弹弹道中段的制导律使用。

Based on the guidance information precision characteristic of the middle trajectory of muhimode guidance missile with Doppler radar seeker and infrared imaging seeker, a guidance law was designed according to the nonlinear robust control theory. Simulation results show that the guidance law is robust to the measure disturbance of missile-target relative distance, and is also robust to a high maneuver target. So it can be used as the guidance law of the middle trajectory of multimode guidance missile with Doppler radar seeker and infrared imaging seeker.
